Detailed specs for Mini leak-proof-3-layer-case Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL2305 series. MOQ 30. 12h quote, 35-day delivery.
If you are sourcing Mini leak-proof-3-layer-case Wholesale from a Chinese factory, you have probably seen marketing sheets with vague dimensions and a single IP rating. We do the opposite. Every dimension here is measured at the QC station, every rating is third-party tested.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+PC | First Aid Kit |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+PC | Vaccine Carrier |
| WL5020-C | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+PC+PCM | Cold Chain 24h (-20°C) |
The most common model for "Mini leak-proof-3-layer-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Shell material for Mini leak-proof-3-layer-case Wholesale is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -80 ~ +50 (depending on PCM/VIP configuration) °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Our Mini leak-proof-3-layer-case Wholesale buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
For Mini leak-proof-3-layer-case Wholesale, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
We ship Mini leak-proof-3-layer-case Wholesale to 47 countries via FOB Shenzhen, CIF, DDP, EXW. Sea: 12-38 days by region. Express (DHL/FedEx): 3-7 days for samples. Full container load: 28-35 days.

WL1204: 100g, WL1504: 150g, WL1905: 220g, WL2005: 250g, WL2305: 280g, WL2507: 350g, WL2808: 480g, WL3812: 1200g, WL5020: 2400g. Weight tolerance ±5g. Includes foam set but not foam-cut cavities.
Our Mini leak-proof-3-layer-case Wholesale comes in 9 standard sizes from WL1204 to WL5020. Outer dimensions: 120×90×40mm (smallest) to 500×400×200mm (largest). Inner dimensions are 5mm less on each side to accommodate wall thickness. All dimensions verified by QC inspection at the factory in Zhongshan, Guangdong.
Load capacity scales with size: WL1204 up to 5kg, WL2005 up to 12kg, WL3812 up to 30kg, WL5020 up to 80kg static load. Validated through pressure testing at our factory — every batch sampled at 1.5x rated load for 24 hours before shipping.
We publish both. Outer dimensions in mm (millimeters) and inches (e.g., 380×320×120mm = 14.96×12.60×4.72in). Inner dimensions follow the same dual-unit convention. Custom sizes available with MOQ 500.
WL1905, WL2005, WL2305 are all 'Medium' size (~190-230mm outer length) but differ in width and depth. WL1905 is square (190×190), WL2005 is wider (195×170), WL2305 is balanced (230×180). 0.5-1.0mm differences determine what fits — we help you choose during the 12h quote consultation.
